      Pull exofs changes from Boaz Harrosh:
 "These are just 3 patches, the last two are bug fixes on the error
  paths in exofs.

  The important patch is the one to osd_uld which adds sysfs info to osd
  devices for use by user-mode clustering discovery software.  I'm
  already sitting on this patch since before February this year, It is
  important for some of the big installation cluster systems, who's been
  compiling their own kernel just for that patch."

Ugh.  The osd_uld patch already went through the SCSI tree, so this was
kind of pointless.  But at least it has the two small error-path fixes..

* 'for-linus' of git://git.open-osd.org/linux-open-osd:
  exofs: don't leak io_state and pages on read error
  exofs: clean up the correct page collection on write error
  osduld: Add osdname & systemid sysfs at scsi_osd class

      Pull btrfs update from Chris Mason:
 "A big set of fixes and features.

  In terms of line count, most of the code comes from Stefan, who added
  the ability to replace a single drive in place.  This is different
  from how btrfs normally replaces drives, and is much much much faster.

  Josef is plowing through our synchronous write performance.  This pull
  request does not include the DIO_OWN_WAITING patch that was discussed
  on the list, but it has a number of other improvements to cut down our
  latencies and CPU time during fsync/O_DIRECT writes.

  Miao Xie has a big series of fixes and is spreading out ordered
  operations over more CPUs.  This improves performance and reduces
  contention.

  I've put in fixes for error handling around hash collisions.  These
  are going back to individual stable kernels as I test against them.

  Otherwise we have a lot of fixes and cleanups, thanks everyone!
  raid5/6 is being rebased against the device replacement code.  I'll
  have it posted this Friday along with a nice series of benchmarks."

      Pull NFS client updates from Trond Myklebust:
 "Features include:

   - Full audit of BUG_ON asserts in the NFS, SUNRPC and lockd client
     code.  Remove altogether where possible, and replace with
     WARN_ON_ONCE and appropriate error returns where not.
   - NFSv4.1 client adds session dynamic slot table management.  There
     is matching server side code that has been submitted to Bruce for
     consideration.

     Together, this code allows the server to dynamically manage the
     amount of memory it allocates to the duplicate request cache for
     each client.  It will constantly resize those caches to reserve
     more memory for clients that are hot while shrinking caches for
     those that are quiescent.

  In addition, there are assorted bugfixes for the generic NFS write
  code, fixes to deal with the drop_nlink() warnings, and yet another
  fix for NFSv4 getacl."
